PCIE cables for 3080

[didde95]

Hey I'm buying a 2x8 pin powered 3080 and I was wondering if these cables ( https://ibb.co/RBr34HR )  on my 750 watt psu will be enough to power it without risk or do I need 2 seperate 8 pin cables?

It'll be enough if you aren't going for record overclocks, but two cables is better if you've got access to that.

Is there any way to buy an extra one? or do I need brand specific

You can buy individual cables from sites like cablemod.com  

 

Only buy a cable if it says it's compatible with your model of power supply. 

 

Some manufacturers use different pinouts compared to other manufacturers, or different connectors, so a cable from one psu may not be compatible with your power supply. 

 

Even if they're two psu's from same manufacturer, no guarantee they're the same pinout (same order of wires in connectors). Some are better than others... for example Seasonic's power supplies from a few years back until today all have same cables, they went through 3 "revisions" until they settled to this last format

 

Manufacturers like evga and corsair will have lots of different cable pinouts because they use models from various OEMs each with its own pinouts.

What psu do you have? A GOOD quality 750w unit should do the trick but there is the catch if your psu isn't of good quality it may not be able to power the 3080 or it may but not for long before it gives out.
